To all whom it may concern:

Be it known that I, HEINRICH Korrnns (assignor to The Koppers Development Corporation, a corporation of Pennsylvania), a citizen of Germany, residing in Essen-Ruhr, Germany, have invented a new and useful Improvement in Coke Quenching and Load ing Apparatus, of which the following is a specification.

The invention relates to a coke quenching and loading device having improved fea tures of arrangement and Construction, with the object of economically providing for large storage capacity so as to accommodate temporary over-production, or congestion of transportation and the like, at the same time providing for the ready interhandling of the coke between the coke oven, the quenching station the regular screening and loading means and the emergency loading means.

My German application K. 61,514 Vl/lO relates to a coke quenching and loadingdevice with a car receiving the coke pushed out of the ovens, the car having'a slanting bottom and co-operating with a stationary suitable ramp adjoining its bottom, of an inclination approximately less th'a'nthe sliding angle of the col ie, the coke being susceptible of being transferred to the ramp without dropping and therefore without being destroyed or broken up, spreading out there in so thin a layer that it can be quenched subsequently and discharge the vapors as may be required. The invention concerns a development of such a device by providing, alongside of this throw off ramp to be used normally, a second, larger emergency ramp on which the coke can be stored in the absence of cars, while it can be thought, by a conveyor device, either di'-- rectly into the cars or onto the conveying belt of the throw-oil ramp proper which serves tor the regular and usual production and transportation. The arrangement has the following object: lVhile any enlargement of the throw-01f ramp proper for the occasional storing of the coke is counteracted by the fact that a careful embodiment of the same, for instance as regards the feed rollers for the conveying belt and the irrigating devices, would render such a plant too expensive, the supplementary storing ramp can be made much simpler since it is to be resorted to only in case of necessity or in an emergency. .It is not necessary to provide, any special quenching devices here in the first place,and the, feed rollers for the transfer of the coke to the conveying belt can also be omitted; By reason of this simplification the storing ramp can be made suficiently large that any emergency re quirements can be fully met.

In order to make the invention more clearly understood there is shown in the accompanying drawings means for carrying the same into practical effect, the invention not to be limited to the particular embodiment which is herein used for illustration and explanation. In said drawingsing and loaidiirg device embodying the invention.

Fig. 2 is an elevation of the same.

Fig. 3 isan end view on a larger scale partly in section showing a portion of the oven, the coke transferring car, and track, the throw-off ramp and the ordinarily used screening and loading means.

Fig. 4 is a similar view on a smaller scale showing the supplementary storing ramp and loading means. l

According to the main application referred to, in front of the coke oven a, on the track 0, the platform car 6 runs and into which the coke is pushed from the Ovens and in which the coke is held by the door d. The car is then run to the quenching station e where the coke is quenched in the car. The throw-off ramp 7 which is used during normal operation of the plant, is provided with pin weir and feed roller g. which supplies the glowing coke in well regulated quantities to the conveying belt h. This throw-off ramp is given dimensions large enough to enable it to receive suflicient coke cakes to accommodate the supply between the periods necessary for pushing the ovens and for after-quenching and discharging vapor from the coke. This throw-off ramp can then be built so efficiently as regards every detail that its constant use will be very economical. The conveying belt it takes the coke from the throw-oil ramp to the height of the screening arrangement 2', at a regular loading station, from where the screened coke can reach the railway cars.

Now, in addition to this throw-off ramp proper, a storing or emergency ramp 7" is Fig. 1 ,is a plan view ofa coke quench provided which is built much more simply, by omitting, for instance, the quenching device and the pin weir as well as the feed roller for the uniform loading of the conveying belt. But'the storing ramp f can without undue expense be made so big that it can store great quantities of accumulated coke caused by the absence of cars. Underneath the storing ramp f a conveying belt- 72. is running along to which, in view of the exceptional use, the delivery of the coke from the ramp is effected by hand. This conveying belt 72 is guided into the tower a" at an emergency loading station, so that the coke of the storing ramp can either be loaded from here directly into the railway cars or placed on the conveying belt h of the throw-ofi'ramp f to be normally routed from here via the screening arrangement. In this way a complete provision is made for the disturbances or trouble occurring as interruptions to the normal operation of the plant, without necessitating a complicated and expensive construction;

What is claimed is 1. A coke quenching and loading device comprising, in combination: a coke oven; a car for receiving coke pushed from the oven, said car having a slanting bottom; a quenching station for quenching the coke in said car; an inclined throw-oil ramp adapted to receive the quenched coke from said car; means for conveying the coke from said ramp to a screening apparatus; an auxiliary ramp of relatively greater capacity adapted for use in emergency; means associated with said auxiliary ramp adapted to transfer thecoke on said ramp to either railway cars or to the conveying means of said first mentioned ramp. 1

2. The combination of a coke oven, an inclined throw-oil ramp, a storage ramp, a track between said oven and ramps, a quenching station by said track, and a car on said track adapted to receive the coke from the oven and carry said coke from the oven to the quenching station and then to said ramp, said car having a bottom inclined at an angle not greater than the angle of repose of said coke, the lower edge of which bottom is arranged to deliver coke to said ramp, said car also serving said auxiliary ramp.

3. In a coke-handling construction, the

combination of a coke oven, a track arranged by the same, a car having a slanting bottom and on said track, a quenching station arranged by said track, a slanting cokereceiving ramp arranged at the opposite side ofthe said track from the oven, an extended coke-storing inclined ramp, a screening and loading station, and means for transferring coke from either of said ramps to said loading station. I

4:. In a coke-handling construction, the combination of a coke oven, a track arranged by the same, a car on said track for receiving and transferring coke from said oven, a quenching station arranged by said track, a slanting coke-receiving ramp arranged at the opposite side of the said track from the oven, coke carrying and loading means for said receiving ramp, elevated coke-screening and loading means to which said carrying means is arranged to deliver, a loading track "for cars to be loaded ex tending by said screening and loading means, an extended coke-storing inclined ramp arranged by and between said tracks, an emergency elevated coke loading means by said loading track and having also means to deliver coke to said carrying means, and a second coke-carrying means extending by said storing ramp and thence to the upper part of said emergency coke loading means.

5. In 'a coke-handling construction, the combination of a coke ovien,'a track arranged by the same, a car having a slanting bottom and on said track, aquenching station arranged by said track, a slanting cokereceiving ramp arranged at the opposite side ofthe said track trom'the oven,-coke carrying and loading means for said receiving ramp, elevated coke-screening and loading means to which said carrying means is arranged to deliver, a loading track for cars to be loaded extending by said screening and loading means, an extended coke-storing inclined ramp arranged by and between said tracks, an emergency elevated coke loading means by said loading track and having also means. to deliver coke to said carrying means, and a second coke-carrying means extending by said storing ramp and thence to the upper part of said emergency coke loading means.
